A compact orifice meter/flow conditioner package
- Novacor Research & Technology Corp., Calgary, Alberta (Canada)
Flow conditioners have been the center of attention within the natural gas industry for several years. Their importance stems from the fact that, in the presence of existing installations such as elbows, accurate orifice metering can be obtained, within a specified meter length, only if the flow non-uniformities are eliminated. The tube bundle has, thus far, proven to be ineffective in terms of repeatability and reliability. Thus, NOVA embarked on the mission to find a flow conditioner which would, within the shortest possible meter length, provide accurate and repeatable metering. Of the several flow conditioners discussed in the literature, the approach adopted by Laws, based on screen theory, is best suited to achieve the desired results. However, the Laws flow conditioner has some functional flaws, for example, the claim of a fully developed flow with no account for the effect of Reynolds number. Hence, NOVA has re-designed and modified the existing Laws flow conditioner has some functional flaws, for example, the claim of a fully developed flow with no account for the effect of Reynolds number. Hence, NOVA has re-designed and modified the existing Laws flow conditioner using screen theory. This program, initiated in 1991, has resulted in a perforated plate flow conditioner sandwiched in a meter run with an overall length of 13D.
